Fig. 14 showing the filling plate inserted in the edge of the screen side and thev covered opening through the grooved inner edge of the frame side for the operating lever. j

Like characters of reference refer to correspondingr parte in the several views.

The numeral 10 designates the tubular sheet metal screen frame which is cut and bent from the flat sheet metal strip by means of suitable dies so as to form the lengthwise groove 11 which opens sidewise nlongthe inner edges of the frame sides to receive therein the screen fabric 12 which is` held in place by the spline or holding stri 13.

he screen frame comprises the top cross rail 14. and the bottom cross rail 15 with the outer Stiles or lateral frame sides 16 and inner Stiles or central frame sides 17, and the central cross rails 18 in the screen frames 10 which are of sullcient length to need seid central cross rails 18. The outer Stiles or framesides 16 have the rounded outer edges 19 and the central Stiles or frame sides 17 have the interlapping astragals 20 which are preferably made by a return bend folded in the corner of the sheet metal tubular frame side 17, as shown in Fig. 2.` The cross rails 18 are preferably made of two sheets of metal with the` grooves 11 along the inner side thereof, which groove 11 extends around the entire frame and enlarges inwardly.

The corners of the screen frames 10 are preferably mitered and are preferably united by soldering or welding though their maybe united by any other suitable metho for example, sweating, bolting or screwing. Each of said corners is provided with an angular tubular corner brace, which in those corners where a ivot pin or spring bolt is needed the 'tubu ar corner brace is in the form of a combined brace and bolt barrel 21, as shown in Figs. 8-11, and in those corners wherein the pivotpin or spring bolt is not needed, the simple tubular corner brace 22, shown in Figs. 1 and 13, is used.

The tubular corner braces 21 and 22- are made from theflat sheet metal as follows: The combined corner brace and bolt barrel 21 is formed from the flat sheet metal blank, as shown in Fig. 11,` and has the central iortion 23 which is formed into the tubular liolt barrel 24 for the s ring bolt 25 and has the outwardly exten ing flanged edges 26 which brace against the inner Walls of the frame side. The two Wings 27 and 28 of the Hat sheet metal blank extend out from the opposite sides of one end of thepentral portion 23. The win? 28 is sntllciently larger than the wing 2 so that when they are formed in the channel shape and folded into one another in the tubular form the wing 27 shuts into the wing 28, suitable cuts being made at the corners adjacent the portion 23 to permit the folding of the Wings 27 and 28.

The end 29 of the barrel 24 is closedsufficiently to hold one end of the coil spring 30 around the bolt stem 31 so that said coil spring 30 bears against the end 29 at the one end and against the bolt25 at the other and works freely back and forth around the stem 31 Within the barrel 24 holdin the bolt 25 norm lly in the extended position. The inner en' of the bolt stern 31 1s pivotally attached to the lover 32, which lever 32 is pivotallymounted in the screen frame side through the tube 33 which crosses the bottom of the groove 11, an opening 34 being provided'through the flange 35 which forms the inner lwall of. the groove 11 on the screen frame side. The mounting of the levers 32 and pivotal connection 37 to the stem 31 is attained through an opening 36 in tho curved edge 19 of the outer frame side/16. At the upper and lower ends of the openin s 36 the rounded frame side 19 is inset su ciently, as shown at 38, to receve the curved plate 39 which fits smoothly into the opening 36 because of boing inset so that said plate 39 can be brazed or soldered into place and finished smoothly along with the rest of the edge 19, as shown in dotted line .in F ig. 14. This arrangement permits free access to the end of the bolt stom 31 so that the inner end ol' the lever 32 can be pivotally attached at 37 to said holt stein, as shown in Fig'. l,

The simple tubular corner brace is formed from the blank pattern as shown in Figs. li' and 13, the Wings lohiling, into one another in t"substantiully the saine manner. as the conibned corner brace and bolt bar rel 21. Both of these corner braces are dcsigned to lit snugly within the tubular frame side to brace the sides of the saine as Well :is strengthen the corner of the frame.

In order to removably hinge the screen in the window freine, a combined corner brace and bolt barrel 21 is outer corners ofthe pair of screens to there-- by hinge said scrcons'in the easement frame. Une of the combined corner braces and bolt barrels preferably contains :i lixcd pivot pin 40 at the upper or lower corner, and the opposite corner has a springholt 25 so that said spring holt 2.5 may be withdrawn thereby ,permittingr the outward movement of the screen frame withdrawing the fixed pin 4l) from its pivotal hold in the i'fasoment. One of Athe central frame sides 17 is provided with a pair of siring bolts 25 while the other frame side should have a spring latch 41. The spring.,r bolts 25. for the central frame side 17 are preferably arranged with levers, 32 adjacent one another so that thev can be operated with one hand. The ends of the holt. stoms 31 are connected to the inner ends of the levers by links 4.2 which intcrcross so that said levers 32 will withdraw the bolts 25 when they nre pressed toward one another.

ln large size cusement screens that are hinged, ib is usually necessary to hinge the l'ruine side' midnay between the pivotal ends of the saune. For this purpose a strong?,r strap hinge is provided by insettinggj the curved sheet metal frame sido 19 as shown at 43 and providing the slots. 14- for tin insertion of thv Strap piece 45, which strap picco is provided with holes 4G therethrough for the attaching screws to the window fran-1c 49. A bolt 47 is provided which is cui away at 4R the sanne as the insctll so that said inset 43 can he attained by prossiin.;` ihc shot-t nulal down into the ont around lhiI holt as shown in Figs. 3 `und i", al'tcr which Ihr a nd easily inserted. :as shown in Figs. l and This priiividrs a ;.-ivotu.l hinnjiui: ui' the frame side with an extended hearing therein so that tho i'rnnie side 3:. strengthened and held stiflly in lino 'with the piwtnl pins or bolts .25 and 4U.

lt apparent that ih wel nation bolt barre-l und corner inane tf mush-i in rast or otherwise made from mrlni and serve e. good purpose, hut it would be more expenstrrp piece -li can, he quickly provided for rc1-ich of the i'so sive und not as light and strong as the fold- `ed sheet metal, which is accordingly preferred.
